APPARATUS FOR PURIFYING WATER.

SPECIFICATION forming part ofv Letters Patent No. 700,420, dated May 20, 1902.

' Application filed November 16, 1901. Serial No. 82,577. (No model.)

der No. 9,201, dated May 3, 1901,) of which the following is a specification.

This invention relates to apparatus for the treatment or purification of feed-water by the addition of reagents to form a precipitate to which the oleaginous and other impurities aggregate, and thus facilitate removal by filtration, decantation, or otherwise or by the ad dition of softening agents or other chemicals for the treatment of water for feed purposes, and has for its object to enable this j classof apparatus to be successfully used in marine installations and in other cases in which it is subjected to movement. in cases where apparatus of this kindis subjected to movement, as in marineinstallations, the working of the system is more or less inter fered with and either rendered unreliable.

or impossible. This is particularly the case with the revoluble-distributer described in my Patent No. 667,127, dated January 29,

'1901, and the solution-making apparatus such as, for instance, describedin Andersons patent,-No. 649,035, dated May 8,1900,

which I have found require to be maintained at all timesin a horizontal position as far as possible to insure a satisfactory working.

The present invention consists, therefore,in so mounting or supporting on gimbals or the like or otherwise freely suspending the vessole for dividing or distributing the crude water and for making and delivering the mate- I have found that scribed in my Patent N 0. 667,127 and the solution-making apparatus described in Andersonspatent, No. 649,035, before referred to.

In the accompanying drawings, Figure l isa front elevation, partly in section, showing the distributer, solution making apparatuses, and treatment-tank, the latter, together with its mixing-tubes, being shown broken to economize space in the drawing. Fig. 2 is an end elevation, partly in section, of the apparatus shown in Fig. l.

I Fig. 3 is a detail top plan view of the distributing-trough around the tank.

A is the pipe bringing the total crude W3. ter to be treated.

B is the distributer, described in my aforesaid patent and consisting of a buoyant vessel, which receives the water from the pipe A. This vessel B floats in a tank 0 and is caused to rotate therein upon a vertical guidespindle D by the reaction of the escaping streams of water delivered through its tangential nozzles E into an annular trough F, surrounding the tank 0.

This trough F is divided by radial partitions F into compartments of different sizes, as shown in Fig. 3,

which'receive the liquid in proportion to their size in a ratio selected according to the feeds into which the liquid is to be divided or distributed. f The crude waterthus divided is delivered from the larger compartment or compartments into the treatment-tank J and from the'smaller compartment or compartments into one or more solution-making apparatuses L, which deliver it in the form of chemical solutions into the said treatment.-

tribute'r'B CFis thereby always maintained in a horizontal position. I prefer to form the lower portion of the revolublevessel B and also the tank O, in Which the same floats, of

a bowl shape, as shown, and provide the tank O with one or more pockets or other passages G to bring the liquid from the compartments of the annular trough F to delivery pipes or nozzles H, which I prefer to arrange near the center of the tank-bottom. In the example shown in the drawings these pockets G and delivery-pipes H are shown arranged only for the larger compartments of the trough F, the smaller compartments for supplying the solutioners L being provided with flexible pipes K, leading to the solutioners.

A separate hopper or funnelshaped receiver 1% is preferably rigidly supported below the distributer, with its mouth of sufficient size to allow free play to the said delivery pipes or nozzles II, which thus hang within it. Any number of them may be used, or a single receiver B may be subdivided by partitions, as shown, for instance, by the single partition S. In the case of marine installations the pipes H should have a much larger play in the direction of roll of the ship, as seen, for instance, in Fig. 2. than in the direction of pitch, as seen in Fig. 1, the mouth of the receiver R being dimensioned aecordingly. The receiver R may also have a lip U turned inward on its upper edges to prevent the liquid splashing over. The tank or tanks J for mixing and treating or settling and storing the water, which are not usually dependent on a horizontal position for a satisfactory working or which are of such size and weight as to be ill adapted to the suspension mounting of my invention, may be placed directly below the said funnel-shaped receiver R, as shown in the drawings, or pipes with funnels or bell-mouths may be so placed as to directly receive and conduct the water or solutions to where required. The solutioners L or other analogous apparatus or vessels are similarly provided with gimbals M N P, supported on brackets O in the same way as the distributer, and they may be used in connection with a separate funnel-shaped receiver similarto the receiver R, before described, or may deliver directly into the mouths of pipes, tanks, or treatment vessels, as desired. The drawings show the delivery from the solutioners L into the treat ment-tank J by means of flexible pipes T, taken from the trunnions P, which are made hollow for that purpose.

\Vhere two reagents are used for treating the water, two mixing-tubes I are provided in the tank J, and the water which is delivered from the receiver R by pipes or nozzles V is mixed. in the tubes I with the chemical solutions brought from the solutioners L by the flexible pipes T, which lead each to a dif ferent mixing-tube. The water and chemicals pass out of the bottom of the tubes I through slots "W into surrounding tubes X and rise up in the latter and pour over the top into one end of the tank Jand then pass through perforations Z in the bottoin of a partition Y into the main space of the tank J. In this way the water is treated in a successive manner first with one and then with the other chemical, as the two chemicals only come togetherin the tank J after being thoroughly mixed with the water first in the separate tubes I, and a proper action is attained. The treated water in the tank J may now have the impurities removed by filtration or by settling and decanting.
